基于近年来我国开展的高速铁路验收调查和专题研究，对实际运行速度300 km/h高速铁路的噪声辐射水平进行了现场实测及分析。初步研究结果表明：目前运营速度为300 km/h高速铁路噪声辐射水平为90～94 dB(A)；高速铁路噪声辐射水平与动车组和线路结构有关，例如：由于桥梁线路结构的差异，京津城际和武广高铁的噪声源强低于京沪高铁约4 dB(A)。

This paper presents an experimental study and analysis on noise source level for 300 km/h high-speed railway. It is shown that, noise source level is between 90~94 dB(A) for 300 km/h high-speed railway;noise source level for high-speed railway is related to characteristics of train and line structure. For example, because of the difference of the bridge structure , noise source level of Beijing-Tianjin and Wuhan-Guangzhou high-speed railway is about 4 dB(A) lower than Beijing-Shanghai high-speed railway.
